The product is the lean portion of the meat in the leftover material from cuts. High in fat, the fat is removed by centrifugation, as noted in the linked article.

Yes, it looks unpalatable, but when cooked, no worse than hamburger and probably better than what is in most weiners, hot dogs, bangers, bratwurst, etc.

It does have the protein content, and is edible, falling within the budget of cash-strapped schools, but those of us who can afford better meats sneer at it.

Leeneia's assessment stands.
